1 Claim. (01. 219-38) My invention relates to improvements in electricheating devices which areparticularly adapted for use in electric firesand the like.

The objects of the invention are to provide means for inducing aircurrents to flow upwards adjacent the heated element with relativelyhigh velocity whereby the heat is rapidly distributed about the roomwherein the fire is used, and also to provide means for discharging awater vapour into the air current.

The invention consists essentially of a vertical tubular body heated bya suitable electrical element capable of inducing an up-current of airtherethrough, and means for adding a water va- 15 pour to the aircurrent, as will be more fully described in the following specificationand shown in the accompanying drawing, in which:-

Fig. 1 is a sectional view of the invention adapted for use as anelectric'fire. I

Fig. 2 is a detail sectional view of the heating element and the watervapour tube.

In the drawing like characters of reference indicate corresponding partsin each figure.

The numeral .1 indicates generally a portable fire housing consisting ofa base plate 2 supported on suitable legs 3, a back plate 4 forwardlycurved at its upper extremity to deflect the heat generated outwardlyinto the room inwhich the fire is in use, a pair of vertical end panels5 and a shallow grille or open front panel 6. V

The grille 6 extends but a short distance above the base plate 2 and isfitted at the front with a downwardly projecting hood 7 and at the rearin substantial alignment with said hood with a bafile plate 8. Thegrille 6 is preferably hinged to the base 2 as at 9 to afford access tothe interior of the housing.-.

Removably fitted upon the base 2 is a water pan 10-having a loose cover11 which supports a plurality of tubes 12 corresponding in number to thenumber of elements in the fire. Each of the tubes 12 is fitted at itsbase with a bell 13 which is adapted to be immersed in the water of thepan. Fitted inthe back of thehousing is a plurality ward flow of airtherethrough due to its high ofpairs of terminal clips 14 which aresuitably insulated and connected by wires 15 to a plug fitting or switchnot shown to which the service wires are adapted to be connected. I

A plurality of heating elements generally indicated by the numeral 16are provided, each of which consists of a porcelain tube 17 fittedatopposite ends with metallic clips 18 which are connected together by asuitable resistance wire 19 preferably arranged in a spiral around thetube. Each of the clips 18 is provided with a metallic plug 20 which isadapted to be pressed into the terminal clips 14 to connect theresistance in the electrical circuit.

The invention functions in the following manner.

When the current is switched on, the resistance wire 19 becomes heatedand heats the tube 1'7 which being open at both ends induces anuptemperature. The air is' drawn in through the grille 6 and-after beingheated in the tube is discharged and deflected by the back 4 into theroom. The tubes 12 are heated to a relatively high temperature and onaccount of their high conductivity heat the water in the pan 10 inducinga water vapour to rise therefrom and pass through the tubes to mix withthe heated air discharged from the tube of the heating element.

What I claim as my invention is:

An electric fire comprising a tubular refractory element supporting anelectrical resistance capable of connection within a circuit, means forsupporting the element, a water container below the tubular element, ametallic tube extending upwards through the tubular element andprojecting into the water container whereby the tube 7 when heated willevaporate the water and cause the vapour to flow upwards therethrough,said metallic tube being of such small diameter as to afiord an annularspace between it and the walls of the tubular refractory element, saidannular space serving as-a passage for the up-fiow of air.
